For Pull data from REST API with Authentication Should I Use Content Pack

We are using our own Rest Api Authentication .
In our scenario first Http Post request is sending with username and password ,
Response of first request have some tokens in its header .
Second Http Post request is using header tokens of first request's response. Response of second request have some tokens in its header and we are sending these tokens and set-cookie parameters to Third Http Post request . And coming datas in this way.

My Questions :
Should i use Content Pack because of i need Header parameters when sending and taking requests?
Or
Should i get Header parameters of responses and reuse them to send another request by writing M Query as Custom Data Connector?
Or 
Should i use Content Pack and Custom Data Connector together?
